oeassa Specification of Letters Patent. Patented Apr, 28, 1914-,

, Application filed September 1, 1916. Serial No. 580,126.

Be it known that 1, CHARLES MEssIoK, a citizen of the United States,.residing in Hackensack, county of Bergen, State of New Jersey, have invented a new and useful Improvement in AntislipStair-Sheets, of which the following is a specification.

Objects of the invention'are to provide a cheap yet efiicient long wearing non-slipping rust proof tread for Stairways, platforms, etc.

The invention comprises a hard metal .base plate having a prepared surface (such as, for 1l1St111C(-);1S'plOV1(led by the thin tin surface coating on a heavy gage tinned iron plate, which is adaptedto facilitate t e intimate union of the plate with a relatively thick superimposedcoating of rust resisting lead or equivalent) and a lead coating on the plate with grains of carborunduin or the like wear resisting and antislipping element "impregnated in the lead on the top or" the plate to form a tread surface.

Referring to the accompanying drawin 2 Figure l is a. perspective View of the Fig. 2 is a cross section of the tread showing additional details ,or modifications. I

Upon a step 1, is mounted iny tread 2,

which is composed of several elements. The base of my tread is a heavy tin coated iron plate, 3, upon the surface of which is superimposed a coat of lead. The relatively thick coating of lead 4-, is impregnated with particlcs of carborundum or other grit, in order that it may form a non-slipping surface for foot wear. in Fig. 2 downward extensions of lips lead interlock with punched up formed the plate to mechanically attach the plate 3, With'the lead, it the right of this Fig 2, '7' indicates a portion of the trend which ishent down to form a nosing fontlie step.

- lily tread may be cast by means oi a heated mold process somewhat similar. to that described in my application, Serial Number 572,651, filed July 18, 1910 for method for making antislip treads, obvious Variations of he made in accordance with progress of the art.

comp-r1 i I claim r 1. A friction surface, wear resisting body comprising a tough metal plate whose surface has been prepared to increase its adhQSIVGHGSS for lead and a coating through- (gut the wearing surface, of lead, in which iriction causing or wear-resisting particles are distributed.

2. A friction surface wear-resisting body comprising a tough metal plate coated throughout its wearing surface'with leadin which friction causing or wear-resisting @FFlQEQ particles are distributed, said coating being secured to said plate throughout their opposing surfaces by an intermediate thin coatin intimately adhesive to the surface of the plate and lead coatin 3. A friction surface, wear-resisting body comprising a tough metal plate whose surface has been prepared by tinning to in crease its adhesiveness for lead anda coating throughout the wearing surface, of lead, in which friction causing or wear-resisting particles are distributed,

4:. A friction surface wear-resisting body comprising a tough metal plate coated throughout its wearing surface with lead in which friction causing or wear -resistingparticles are distributed, said coating being secured said plate throughout their opposing surfaces by an intermediate thin ,t in coating intimately adhesive to the surface of the plate and lead coating,

5. ii-friction surface, wear-resisting body coinprisinga tough metal plate having a surface adapted to render it intimately adhesive lead and a coating throughout the weari surface, of lead, in which friction 2, or wear-resist ng particles are dis l I riction surface, wear-resisting body rig a toughmetal plate, a thin coating f to increase its adhesiveness for lea a coating throughoutthe wearing surface, of lead, in which friction causing or wear-resisting particles are distributed.

Y Fiction surface, wear-resisting body comprising a tough metal plate having a surface adapted to render it adhesive to lead, a coating of lead, friction causing or wear-resisting abrasive particles distributed and? embedded in the lead and? intime'ge 'ellic adhesion between the plate and Lee lead throughout the bottom 01% the Wearing surface.

8. A tread consisting 015a tough metal base p13? having a surface adapted t0 render it adhesive to lead, 2L lead mating having friction particles embedfledi r se tributed. therein and intimate ee'ihesive me tame attachment throughout the base of the lead and the surface of the plate.
